It is through the movement of these electrons that electric current flows and light is created. If the electrons' mobility could be manipulated, then new properties could be revealed. In considering materials to introduce to affect the movement of the electrons, scientists evaluated the source of materials with an eye to supply, especially materials that do not harm the environment. Like salmon sperm...

News is reporting that the International Bureau of Weights and Measures in Sevres, France (southwest of Paris) has discovered that the 118-year-old platinum-iridium cylinder used as the international standard for the kilogram is losing weight. So far, only about 50 micrograms, but physicists are baffled as to why. It is used to verify the weight of other standard kilogram weights used by other countries, and this could mean problems if kilogram has actually gotten lighter, but mainly for scientists and engineers. This is spurring discussions of replacing the current weight with something new which might be more stable, like a sphere made out of a Silicon-28 isotope crystal."
